Electromagnetic Compatibility

Elevator requirements within the European Union are:


EN 12015:1998 Emission
EN 12016:1998 Immunity


The 1998 versions are current at the time of publication of this guide (December 2004). Revised versions are expected to
be published early in 2005 (see below).


The emission limits in EN 12015:1998 are similar to EN 61000-6-4, which is met by Unidrive when using the recommended optional input filter and screened motor cable. Full instructions are given in the Unidrive EMC data sheet.


Particular notice must be taken of the recommendations where a device such as the output contactor must be included
in the motor circuit. The EMC data sheet gives recommendations for managing this situation, which must be
followed carefully.The output contactor and any associated unscreened wiring, and the contactor coil wiring, must be kept
well spaced from the input wiring to the filter, otherwise stray capacitive coupling will cause increased high-frequency
emission from the power input wiring.
Unidrive meets the requirements of EN 12016 unconditionally.


Future revisions of EN 12015 and EN 12016
Please refer to your local Drive Centre/Distributor for information regarding EN 12015:2005 and EN 12016:2004.
